  • An alternative technology to vacuum dehydration
    is dehydration by air stripping (Figure 4), a
    process that removes water as well as gaseous
    contaminants in the oil.

3
  • Not only does it remove free and emulsified
    water, but also dissolved water down to less than
    100 ppm.

4
  • Because of its ability to degas, it is also
    suitable for removing hydrocarbons in seal oil
    systems.

  • Air stripping works by drawing air or nitrogen
    gas into a stream of heated oil, which mixes in
    and absorbs the water and gasses within the oil.
    The oil/air is then expanded to release the air
    or nitrogen, which takes the impurities with it.

7
  • Generally, the water removed will be of a
    reasonable quality, sufficient to allow it to be
    drained off in the normal network without special
    disposal requirements.

  • The exhaust air and gasses are also controlled to
    minimize the oil vapour released.

10
  • Just like vacuum dehydrators, cost is an issue
    with air stripping. However, its advantage is
    that it costs less to maintain than a typical
    vacuum dehydrator because it has fewer moving
    parts.

11
  • The fact that it can also remove other gaseous
    impurities, as well as dissolved water, makes air
    stripping technology an effective alternative to
    vacuum dehydration.
